SPECIFICATION formingpart of Letters Patent No. 419,592, dated January 14, 1890.

Application filed May 4, 1888. Serial No. 272,789- (No model.)

To all whom it may concern:

Be it known that we, THEODORE A. MEYSEN- BURG, of St. Louis, Missouri, and WILLIAM GARRETT, of Cleveland, Ohio, have jointly made anew and useful Improvement in Spike- Rod-Making Machinery, of which the following is a full, clear, and exact description.

The improvement relates to that class of spike-rod-making machinery in which the spike-rods are made from old-rail piles or steel billets. In such machinery, as the rolls have hitherto been made and combined into a train, seventeen passes have been needed to reduce the pile or billet to the desired rod, and so much time is thereby consumed a reheating of the metal becomes necessary. Aside from the objection to the time consumed in the protracted operation, the metal of old rails is liable to lose strength by continued reheating.

By means of the present improvement the operation of reducing an old-rail pile or steel billet is shortened, and but a single heating of the metal suffices.

It consists in so constructing .the roughingrolls and so combining theminto a train with the finishing-rolls, all substantially as is hereinafter shown and explained, as to provide for a greater reduction of the metal while in the roughing-rolls than hitherto has been attainable, and so as to enable the reduction of the pile to a spike-rod to be accomplished with thirteen passes and the operation of reducing the metal to be a continuous one, all as set forth in the annexed drawings,.making part of this specification, in which- Figure 1 is a plan of the improved train, the line of arrows indicating the movement of the metal. Fig. 2 is an elevation of the train from the line 2 3, Fig. 1. Fig. 3 is an elevation of the train from the line 3 3, Fig. 1; and Fig. 4: is an elevation of the principal portion of the finishing-rolls from the line 4 4, Fig. 1. Fig. 5 is an end elevation of the old-rail pile from which the spike-rod is produced; and Figs. 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, and 18 respectively represent the shapes the metal assumes successively in passing through the train. All of said lastnamed views are cross-sections, saving the last, which is a view in perspective.

The same letters of reference denote the same parts.

inches by two and nine-sixteenths inches; in 6 the next pass 0 to an oblong one and ninesixteenths inch by two and eleven sixteenths inches; in the next pass 0 to a square one and five-eighths inch each way; in the next pass 0 to a square one and three-eight-hs inch each way; in the next pass 0 to a square one and one-quarter inch each way; in the next pass 0 to a square fitteen-sixteenths of an inch each way, and in the next pass 0 to a square thirteen-sixteenths each way-that is, considered generally, nineteentwentieths of the entire reduction is accomplished by. means of the roughing-rolls. The thirteen-sixteenths rod now formed is carried from the roughing-rolls around to a two-high 5 rolls D, Figs. 1, 2, and 3, arranged at the side of the roughing-rolls and preferably in line therewith, and by means of the single pass d therein the rod is further reduced. The rolls D are sixteeen inches in diameter, and from 8 them the reduced rod is carried to and passed through the only pass 6, Fig. 3, of the rolls E, Figs. 1 and 4,'which are located opposite and about fourteen feet from the rolls D, and the rod thereby further reduced. The rod is then g isolated rolls H, which are nine inches in diameter, Figs. 1, 2, 3, and 4, and by means of the single pass It therein the spike-rod ninesixteent-hs inch square is finally produced, and all at a single heating.

The advantage of the rolls constructed and arranged as described is that but one heating of the rail-piles from which the spike-rod is made is,by means of said construction and arrangement, rendered necessary, thus obviating the injury to the metal caused by re-- heating, and saving time, as but thirteen passes are necessary to complete the rod.

lVe clai1n- The herein-described spike-rod-making mechanism, comprising the roughing-rolls C, having the passes c c e o o e" 0 the rolls D, aligned with the roughing-rolls at one end and having but one pass, the finishing-rolls E F G, aligned with each other parallel to the rolls D and each having but one pass, and the finisl1ing-ro1ls H, setat right angles to the rolls E F G and having but one pass, the passes of said rolls gradually decreasing in size from the pass 0 to that of the rolls I-I,substan tially as specified.
